Seeing a shooting star means that a meteor is plummeting toward earth. The glowing appearance is caused when the meteor's surface catches on fire upon entering the Earth's atmosphere. A shooting star, therefore, is not actually a star.
Although the idea of space debris plummeting toward Earth seems a bit intimidating, meteoroids, which are meteors that are still floating through space, are much smaller than comets or asteroids. Although there are some records of meteors actually making impact on the ground and causing damage, the vast majority of them are either completely consumed by fire before hitting the ground or are extremely insignificant in size and cause virtually no damage.Learn More

Scientists will never know the farthest star from Earth, as the star is so far away that its light has not, nor will ever, have enough time to reach Earth. Even the stars within the visible universe are far too numerous to count, but the farthest one that humans have ever detected is about 55 million light years away. This incredibly distant star is called SDSS J 122952.66 +112227.8.Full Answer >
Meteor showers occur regularly as Earth's orbit takes it through areas of space debris. As the debris enters the atmosphere, heat causes it to burn up, resulting in the streaks of light that are commonly known as shooting stars. The debris itself is most often leftover material from comets, which leave debris paths as they orbit the sun.Full Answer >
Multiple private companies offer, for a fee, to "register" names or titles of ownership for stars.
